ceive the packets as they pass from the main feeding roll. The specificconstruction and operation of these moistening `rollers 21 and has beenclearly sift forth in the above referred to application, and as theyform no part of the present invent-ion, further description of the sameis deemed unnecessary. f The roller 22 is connected for operation to themain feeding roll 12 by a chain 23 held taut and out of the path of thepackets by an idler 24. A platform 25 bridges the space between the mainfeeding rollv12 and the spacin roll 19'and the moistening rollers 21 an22, the plat-form 25 directing the packets between the meisteningrollers 21 and 22.

The frame 1() carriesI anL initial feeding roll 26 having a preferablyrubber periphery and projecting up through a transverse slot 27 formedin the table 11, at a. point spaced rearwardly from the main feeding Theinitial feeding roll 26 projects slightly above the upper surface of thetable 11, and engages the lower face of the lowermostpacket to impart aforward sliding movement to the same. The initial feeding roll 2G isconsiderably reduced in size relative to the main feeding roll 12, andreceives movement therefrom in a lforward direction by a chain 28 heldtaut beneath the table 11 by an idler 29. As may be seen from Fig. 1 ofthe drawing, the initial feeding roll 26 is so geared to the mainfeeding roll 12 by the chain 28 that the initial feeding roll 26 isrevolved continuously at a relatively high rate of speed as compared tothe angular velocity of the main feeding roll 12. The initial feedingroll 26 is mounted upon a shaft 30, serving as a tie rod in the frame10. At one side of the table 1l is a guide 31 preferably fixed upon theframe to hold the packets in superimposed relation upon the table, whilean adjustable guide 32 is slidably disposed upon the table Il andpreferably has connection with the .shaft or tie rod 30 to hold theguide 32 firmly v, hen adjusted. From this structure it will bcunderstood that the initial feedin roll 26 has a relatively high angularve ocity as compared with the. angular velocity of the main feeding roll12, and that therefore the lowermost packets which bear upon the initialfeeding roll 26 are fed quickly and uninterruptcdly to the main feedingroll, for a` purpose which will appear from the hereinafter describedoperation of the device.

From the foregoing description it will readily be seen thatthe'operation ofthe ima'- proved device is as follows: A number ofpackets is disposed upon the table 11 against the guide 31 and insuperimposed relation. The packets are. pushed forwardly againsttheguard plate 2O and the adjustable guide 32 iS nl ved into positionagainst the oppotion, engages the site edges of the packets. The mainfeedin roll l2 is now revolved, which o eration e fecis the turning ofthe initial feeding roll 26. As the packets rest upon the initialfeeding roll 26 the lowermost packet is moved forwardly over the tablel1 into eni gagement between the main feeding roll 12 and the spacingroll 19. Should, by accident, two packets pass together onto the mainfeeding roll, the separating roll 19, revolving in a backward or reversedirecu per face of the upper packet am forces tfie same backwardlytoward the initial feeding roll 26. This op 'eration admits of thepassage of but one packet at a time to the moistening rollers 2l and 22.When the ackets are piled up upon the bed plate t ey are supported attheir middle portions upon the initial feeding roll 26. The initialfeeding roll 26 therefore, supports practically the entire weight of thesuperposed packets, and there is thus a greater frictional Contactbetween the initial feeding roll 26 and the packets than between thepackets and the bed plate 11. The forward movement of the initialfeeding roll 26 forces the packets against the guard late 2() and thelowermost packet forwar ly toward the main feeding roll l2, a distancesufficient to displace the middle portion of the lower-most packet fromthe initial feeding roll 26 to the forward endv hed plate l1. At thistime the lowernmst packet has greater frictional Contact with the bedplate 11 than with the initial feed ing roll 26, and, therefore, theinitial feeding roll 26 no longer elfects the forward feeding of thelowermost packet. The main feeding roll 12 now engages the forward endof the lowermost packet and draws said packet into the machine theinitial feeding roll 26 assistinvf to some extent in supporting therear'en of the parket. The rear end of the packet,which bears againstthe initial feeding roll 26, holds the second lowermost packet fromdirect contact with the initial feeding roll 26, and thereby effects anautomatic interruption in the feeding of the packets from the pile. Assoon as the lowermost packet passes considerably over the main feedingroll l2 the pile of packets is permitted to drop down upon the initialfeeding roll whereby the second lowcrmost packet is given a forwardimpulse resisted only by the separating roll 19. It is thus seen that toeffect the positive and automatically interrupted feeding of the packetsfrom the pile, it is necessary to dispose the initial feeding roll 26 atthe middle of the bed plate 11 so that it will engage the middleportions ofthe superposcd packets of the pile.

The packets may be piled indefinitely upon the table 11 between the0fuidcs 3l and 32 as the improved device feedns the packets I claim asnew is:-- l

1. In eombination with a main feed roll, a rerersely rotatingsepz'tratiu;r roll arranged above the feed roll7 a guard plate disposedimmediately behind the, separating' roll, and a bed plate projt-.etingrearwardly from the top oll the main feed roll adapted to support a pileol superposed parlt'ets, an initial teed roll extending up through themiddle portion ot the bed plate and adapted to .support the middleportion of the pile ot paeltets whereby said initial feed rolt isadapted to move the lowermost paeliet t'ornardly a short distance unt-ilthe forward end ot said packet engages the main l'eed roth the trieAtion between said parket and the bed plate being' greater than theirietion between the initial t'eed roll and the rear end ol' the packetwhereby the partit-t is drawn l'orwardly by the main t'eed toll at aredut-ed rate of speed, the rear end otl the lo\\'eruiost paeket restingagainst the initial feed roll whereby to prevent. eonlaety ot .waidinitial feed roll with the next adjaeent parket.

2. An automatit.l feedingY derive compr-its ing)r a forwardly rotatingmain l'eed roll, a, reversely rotating` separating roll bearing downupon the feed roll, a bed plate extending baelnvardly from the top ofthe main feed roll and adapted to support a'pile of euperposed packets,a guard plate rising from the forward end of the bed plate adjaeent said`separatinlbr roll7 and an initial feed roll extending' up through themiddle ofthe bed plate and adapted to bear against the middle portionot' the pile paelt'ets whereby to prevlllit the. pile of paeltets`bearirnar its tull weight/upon the bed plate and having an angularveloeity greater than the angular reloeity ol' the main feed rollwhereby to iluifldy and uninterruptedly more the lowermoat paeliet tothe main feed roll, a distanee sutlieieut to dispose the middle portionol' said parket forwardly olI the initial feed roll, the t'rietioualeontaet between the bed plate and the lowest packet when moved forwardlybeing greater than the trietional eontaet between the initial feed rolland the rear end of theI paelt'et whereby the movement ot said paeltet.lis' reduced to the speed of the main roll and the. initial feed roll isheld from eontaet with theI next lowermos't packet..
